About AutoRate
Sets the rating for all tracks in your iTunes library according to how often each track is played, and how often each track is skipped. The formula uses an adjustable combination of play and skip frequency (averaged out over the life of each track), and the play and skip count. Tracks that are frequently skipped are penalized, while often-played tracks are given a higher rating. It uses a 10 bin normal cumulative distribution based histogram to automatically scale the ratings so that the mean rating is ~3. Tracks may be rated using half or full star increments.

Both the track play count & skip count are used in conjunction with the length of time each track has been in your library to determine, on a relative basis, how much you like each track.
